Orthodontic Assistant Practice Exam 2026 – Complete Prep Guide

The ideal time for a first orthodontic evaluation is by the age of 7, which coincides with the eruption of the first permanent molars and incisors. This timing is significant because it allows the orthodontist to assess the development of the dental arch and occlusion at a formative stage in a child's growth. At around this age, early detection of potential orthodontic issues becomes possible, allowing for timely intervention if necessary.

Assessing children at this age can help identify problems such as crowding, crossbites, or other alignment issues that might benefit from early treatment, ultimately improving long-term dental health and alignment. Early evaluations can help guide growth and offer preventive measures that can lead to less complex treatments later on.

In contrast, evaluations at younger ages, like 5, may not provide sufficient information since not all primary teeth have erupted, potentially missing key developmental indicators. Waiting until 10 or 12 might delay intervention for issues that could have been effectively managed earlier, possibly leading to more complex treatment in the future. Therefore, the age of 7 is recommended to balance early intervention with the development stage of the child’s teeth and jaw.
